I do think that politics, particularly American politics at this particular time is important to any discussion of global warming, arctic ice, and our way forward. I agree that keeping these discussions separated from more scientific musings might be helpful and have advocated for keeping the politics "below the line", OFF TOPIC,in THE REST Section.
I don't follow this 100% myself, as this post demonstrates, but it should make it easier for those uninterested in politics to ignore those of us who are.
While life sustaining gardens, bicycling and roof top solar all make a difference, convincing the city council to purchase E-Buses, convincing your state or province to dump coal, or pressuring a particular federal government to return to the Paris Accords might be just as important.
Political participation is important to our cause, and politics can get nasty, quickly. Personally I feel that atomic warfare is the most immediate threat we face, and you'll find most of my politics is aimed at reducing this threat in some manner.
1st we return to MAD, even as we cooperate to slow global warming.
If we get #1 wrong, the other numbers don't matter.
